helpp please i'm such a failure​

THIS IS AN COMBINATION REACTION SO3 Combined with H2O to form Sulfuric acid.

When two or more reactants combine to form a single product such reactions are called as combination reaction.

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
